摘　　要：ADμC812是一种新型的集成12位数据采集系统,它在单个芯片内包含了高性能的自校准多通道ADC、两个12位的DAC以及可编程的8位MCU以及三种串行I/O外设接口即:UART串行外设接口、2线I2C串行外设接口、SPI串行外设接口。通过这三种串行外设接口可以进行PC机与ADμC812之间的串口通讯;PC机的串行下载功能实现在线的程序调试;进行多片主从单片机的信息传递。通过串口的通讯ADμC812可以实现与外界计算机和单片机的信息交换,从而实现系统之间的各种控制和操作。The ADμC812 is a fully integrated 12-bit data acquisition system incorporating a high performance self-calibrating multichannel ADC,two 12-bit DAC,programmable 8-bit MCU and three kinds of serial communication system UART serial port I2C serial port and SPI serial port on a single chip. Through three kinds of serial communication system the message can be communicated between PC and ADμC812 the programs can be debugged on the line using the serial downloading of PC the information can be transferred through multi-master multi-slave configurations. Using the serial communication ADμC812 can actualize the communication with PC and exterior MPU in order to achieve the functions of controller and operation.
